HYDRAULIC RAM.

Specification of Letters Patent.

Application filed November 27, 1909.

Patented Oct. 10, 1911.

Serial No. 530,267.

T 0 all whom it may concern:

Be it known that I, JEAN BAPTISTE COUR- TET, a citizen of the French Republic, residing at Romans, Drome, in France, have invented certain new and useful Improvements in Hydraulic Rams, of which the following is a specification.

The object of the present invention is an apparatusfor raising liquids, particularly water to a height greater than that of the fall at disposal.

The apparatus is particularly adapted for use in domestic installations and although of very simple construction and compact it is of great stability and works with a high efliciency.

The accompanying drawing shows more or less diagrammatically apparatus according to the present invention, Figure 1 being a section of part of such apparatus, Fig. 2 a partial section on the line A'A of Fig. l and Fig. 3 a section of a modification.

The water entering through the pipe a, traverses a filter b for removal of impurities and from such filter flows to the apparatus through a double conduit 0 d of a length according to the height of the fall at disposal. In the position shown in the drawing, the two conduits 0 and (Z being under the natural pressure of the water, the valve 6 is closed and instantly stops the flow of water through the outlet f, and the pipe 9, so that a certain quantity of water is introduced into the rising column 2' through the valve h. However at the same time that the valve 6 is closed, the beam y has opened the valve 70 and immediately the flow from the conduit d taking place through said valve, the water flows away through 1 and g, and in its passage carries along the valve 7: which in turn becomes closed whereupon the valve 6 is opened and a further quantity of water is introduced into the rising coliunn 2'. It will be seen that the valves 6 and 7c are alternately opened and closed by the beam 3', and produce at each closure a hydraulic action which lifts one or other of the valves Z and h and forces into the rising column 2' a certain quantity of water which will be used for example at the upper floors of a house, while the conduit 9 will continue to supply the lower floors. In order to control or regulate the descending current of water through said conduit 9, the end closed by the latter is formed as a chamber into which passes the air contained in the apparatus, or carried forward by the water. This air can not pass back to the apparatus. When this chamber is filled, the excess of air is carried along by the descending current. An air chamber m also surrounds the rising conduit 2' for regulating the ascending current. Two discharge cocks 0, 0 may also be'provided, particularly for outlet of air which is contained in the apparatus before operation of same.

It is well understood that the details of construction and installation of the device may be varied according to desire. Thus, the ascending column may be divided into two conduits, and the shape of the beam could be modified, for example it may as shown in the drawing, be provided with a groove p, into which engages a small lever a integral with the rod 1", which again is integral with a handle 8 adapted for actuation from the exterior for facility in operating the apparatus. It will be sufiicient to slightly turn said handle to the right or left in order to move the beam. A small stuffing box 2? will prevent leakage of water or air around the rod '1".

In Fig. 3 a simplified apparatus is shown with only one descending conduit 0 for supplying water. In this case one end of the beam carries a counter weight it acted on by a spring 41 and the apparatus can be placed in connection with a conduit without preparation or particular arrangement.

What I claim as my invention and desire to secure by Letters Patent of the United States is Apparatus for raising liquids comprising two descending inlet conduits for the incom' ing liquid, a rising conduit, anti-return valves between the ends of the inlet conduits and the rising conduit, a chamber positioned below the lower terminals of said inlet conduit, there being ports extending between said conduits and said chamber, valves positioned within said ports and an outlet conduit leading from said chamber and a rocking beam positioned within said chamber and connecting said last mentioned valves,

whereby when one is closed the other is specification in the presence of two Witopened so that the inlet conduits are alternesses. nately placed in communication with the outlet conduit through the latter valves and JEAN BAP? ISTE COURTET' with the rising conduit through the anti- \Vitnesses:

return valves. THEODORE LOIRE, In Witness whereof I have signed this VICTOR GUILLE.
